How to identify running WebSphere process as Dmgr or Nodeagent or Appserver process ?

WebSphere processes are nothing but java application processes started with a long cmdline as below, which contains classpath , command line parameters, the Main java class and the arguments passed to it.

(e.g) Example of a websphere dmgr process in Linux

The normal process to list a process in Unix environment is to run ps -ef and grep the name of the process, if you now the name.(e.g) ps -ef grep java. The issue is that by default the OS will show 80 characters of the process string or to the widhth of the terminal which is anyway 80 by default in most of the terminals, hence if you try to list the websphere java process where different process types like dmgr, nodeagent, appserver all running in the same box you would pretty much get the same string as there won't be any noticable difference because the classpath, etc would be pretty much same for the all process. Hence we need to use the following ps command with addtional parameters for to indentify the respective websphere process.


To determine if Deployment Manager (dmgr) is running ,

AIX : ps -auxww grep dmgr
LINUX : ps -auxww grep dmgr
SOLARIS: /usr/ucb/ps -auxww grep dmgr (Note you need to run specifically from this directory , otherwise you will invoke ps from /usr/bin which will not like the arguments )

Simlarly you can find for other types of WebSphere processes:
To determine if Nodeagent is running ,
AIX : ps -auxww grep nodeagent

LINUX : ps -auxww grep nodeagent
SOLARIS : /usr/ucb/ps -auxww grep nodegent (Note you need to run specifically from this directory , otherwise you will invoke ps from /usr/bin which will not like the arguments )



To determine if AppServer is running ,

AIX : ps -auxww grep <appservername>
LINUX : ps -auxww grep <appservername>
SOLARIS: /usr/ucb/ps -auxww grep <appservername> (Note you need to run specifically from this directory , otherwise you will invoke ps from /usr/bin which will not like the arguments )

(e.g) ps -auxww grep server1 - to list the process of websphere Applicatoin Server named server1.

(e.g) ps -auxww grep WsServer - to list all the process of the websphere installation.
